PUMP.

SPECIFICATION forming part of Letters Patent No. 364,068, dated May 31,1887.

Application tiled September 24, 1885. Serial No. 178,070. (No model.)

To all whom it may concern:-

-Be it known that I, ALBIN WARTH, a citizen of the United States,residing at Stapleton, in the county of Richmond and State of New York,have invented new and useful Improvements in Pumps, of which thefollowing is a specification. y

This invention consists in an improvement l in pumps, as more fully Setforth in the following specification and claims, and illustrated in theaccompanying` drawings, in which- Figure lis a plan or top view, partlyin section. Fig. 2 is a longitudinal section in the plane m x, Fig. l1.Fig. 3 is a similar section in the plane yy, Fig. l. Fig. 4 is atransverse section in the plane z z, Fig. 1. Fig. 5 is a section in theplane indicated by thelineao x', Fig. 4, looking in the direction ofarrow 1 opposite that line. saine plane looking in the direction ofarrow 2. Fig. 7 is a transverse section in the plane y y', Fig. 4.

Similar letters indicate corresponding parts.

I n the drawings, the letter A designates the pump-cylinder, and B isthe plunger fitted into said cylinder. C is the valve-chamber, andD isthe valve. As-shown in the example in the drawings, the valve-chambercan be made in the form of a cylinder, and the valve composed of twopistons, a a', mounted at a suitable distance apart upon the -same stem.Other valves, such as a disk-valve or plugvalve, may be substituted forthe double piston-valve. The cylinderAcommunicateswith the valve-chamberC through ports b b', and the valve-chamber is provided with threeports, c c' 0*, the ports c c being in communication with thesuction-pipe E, and the port tionary. It will be readily seen that forthispurpose a large number of different devices 'may be used, and I donot wish to confine myself to cert-ain specific mechanism for thepurpose above stated; but I prefer to use mechanism such as illustratedin Figs. l to 6, in-

elusive, which enables me to impart to the Fig. 6 is a section in theplunger B a stroke of any desired length, as will be seen from thefollowing description.

The rod G of the plunger B is connected to a carriageor slidingrack-bar, H, which moves in guides I Iii. The guide I is formed in astandard secured to the bed-plate of the pu mp, The guide I I isloosely` Figs. 1, 3, and 4. inserted in a rotating head, K, which willbe hereinafter referred to. Tothe rack-bar H an intermittentreciprocating motion is imparted by a cogwheel, L, mounted on the shaftM. This shaft has its bearings in the head K, which head is litted intoa standard, N, Fig. 4, so that the head can turn in said standard. Thehead K has secured to it a tube, K*, which has itsbearings in thestandard O. Through the tube K`i extends the driving-shaft l?.

On the shaftP is mounted a pinion, d, which gears into a pinion, e,mounted on a shaft, f. The shaft f has its bearings in the head K and isgeared together with 'the shaft M by cogwheels g h. The shafts M andfare'mounted eccentrically in the head K, Figs. 5 and 6, while thedriving-shaft P is concentric with said head.

On the tube Kitis firmly mounted a cog wheel, i, which gears into acog-wheel, j, mounted loosely on a stud, k, and provided with aneccentric wrist-pin, Z, whichconnects by a rod, m, with a lever, n,Figs. 1 and 2.

This lever extends from a sleeve, o, which con nects by a link, r, withthe valve-rod Q.

On the head K are stops s s', which co-op erate with a movable stop, R,extending from a rock-shaft, t, which is mounted in lugs u,

secured to the bed-plate of the pump. A`

spring, o, Fig. 2, has a tendency to throw the stop It into the path ofthe stops s s', and as long as one of these stops abuts against saidstop R the head K is prevented from rotating in the direction of thearrow marked on it in Fig. 2. On the-rock`shaft t is firmly mountedk IOOport or channel b into the space between the two pistons a a and intothe discharge-pipe F, Fig. 2. At .the same time liquid passes from thesuction-pipe through channels or ports c b, Figs. 1 and 2, into thepump-cylinder behind the plunger. When the sliding rack-barbas reachedthe outer end of its stroke it is arrested by the nose f2* strikingagainst the stop g, Fig. 1. A corresponding nose, f2, arrests the motionof the rackbar in the opposite direction. p i

During the movement of the rack-bar in the direction of arrow 2 the camb2, Fig. 3, which is attached to the rack-bar, and which is roofshapedand provided with a iiat apex, acts on the lever a2, and when the ilatapex of said cam arrives over the tip of the lever the rockshaft thasbeen turned far enough to th row the stop R down clear of the stop s,-which up to that time has rested against the end of said stop R,thereby preventing the head K from turning. As soon as the stop R hasbeen depressed, as above stated, the head K turns very little-that is tosay, as far as the dead motion between the teeth of the cog-wheel L andthe rack-bar H will permitand the stop s is brought to overlap the frontend of the stop R far enough to prevent said lever from rising until therack-bar reaches the position shown in Fig. 7. At this point therack-bar remains stationary, but the cog-wheel L is in position to turnround the end of the rack-bar from the position shown in full lines tot-hat shown indotted lines. This movelnent is eiected by .asemi-revolution of the head K, which at that point, being free to turn,follows the movement produced by the action of the pinion d upon thepinion e, which is ineccentric, so that the pinion d acts upon it asupon a crank, Figs. 4 and 5. As soon as the head K turns in thedirection of the arrow shown thereon in Fig. 2 the stop s is moved awayfrom the stop R, and this stop is raised by the spring c, so that itcatches the opposite stop, s', of the head K and prevents the latterfrom turning beyond one hundred and eighty degrees. By thesemirevolution of the head K and sleeve K* the valve D is changedthrough the action of the pinion 'i on the pinion j. As soon as thecogwheel L has passed around the end of the rackba-r the return-strokeof the plunger commences, and is completed in the same manner as thestroke already described.

Instead of arresting the stroke of the head K by the movable stop R andstopss s', I can use ,a dog, l, which swings loosely on the shaft M,Figs. 3, 4, and 7, and bears upon the sliding rack-bar H. When thisrack-bar has been moved to one end of its stroke, Fig. 7, the cogwheel Lturns round the end of the rack-bar until the dog Z2 bears upon theopposite surface of the rack -baryas Aindicated in dotted lines in Fig.7. During the time the wheel L passes round the end of the rack-bar Hthe head K is free to revolve; but as soon as the dog l' is brought tobear upon one of the surfaces of the rack-bar the movement of the headout through the discharge-pipe.

K is stopped. lf the driving-shaft P is turned in the direction oppositeto arrow l, Fig. 1, the pipe F becomes the suction-pipe and the pipe Ethe delivery-pipe. In this case the movable stop R will be brought intoaction.

AAs shown'in Figs. 1 and 2, the valve D can be made to work in a lining,0, which lining is made of metal or other suitable material, and whichlining is firmly secured in the valvecylinder or valve-chamber 0. Thelining 0 is shown as being provided with three setsof openings, t t tik.The openings t communicate with the channel b. The openings tcommunicate with the channel b. The openings t* communicate with theport cf. The lining 0 prevents wear of the valve-chamber 0, and whensaid lining 0 is worn out or injured it can be removed or replaced byanother lining.

The holes t t tif are preferably made so small that they prevent anymaterial entering the valve-chamber which would be likely to interferewith the operation of the valve D, and the packing of the valve D, whichoften may be soft or yielding, is kept from eatchin or tearing, as thelining 0 allows the valve?) to move or slide easily, and the holes inthe lining 0 are so small that the packing of the valve D cannot strikeortear against the edges ofthe holes t t ti.

The Valve-chamber 0 can be connected with the pump cylinder, B by boltsor screws, Vso that said valve-chamber Crean be readily attached to ordetached from the apparatus. The holes t t t* are shown as of oblongshape; but of course they can be madev of any suitable shape-as, forexample, circular, square, or any other suitable form. The valve-chamber0 should be placed beneath or at the side of the pump cylinder, so thatin case sand or sediment or any heavy impurities are in the'pump-cylinder A said sand or sediment or impurities will fall or bedriven by the action of the mechanism through the channels b b and Theaction of the mechanism is thus not liable to become checkedbyimpurities becoming fixed in the pumpeylinder, which might occur ifthe dis-A charge were placed on the top of the pumpcylinder.

If desired, the cog-wheels ij and the eccen IOO IlO

tric wrist-pin Z can be dispensed with and an eccentric can be properlymounted on thetube or sleeve Kl, and by connecting such eccentric withthe valve the movements of the eccentric will operate the valve.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the pump-cylinder and the piston fittedtherein, of a pump-valve, a driving-shaft, P, head K, loosely connectedto said shaft, connection, substantially as herein described, betweenthe head K and the pump-valve, sliding rack-bar H, connected to thepump-piston, a train of gears for transmitting motion from thedriving-shaft to the rack-bar, and a movable stop controlled by themotion of the rack-bar and constructed to retain and to release the headK, substantially as set forth.
